HARVESTER-BINDER.

SPECIFICATION forming part of Letters Patent No. 631,647, dated August22, 1899i Application filed March 17, 1886. Serial No. 195,576. (Nomodel.)

To all whom it may concern:

Be it known that I, SYLVANUS D. LooKE, a citizen of the United States,residing at Hoosic Falls, in the county of Rensselaer and State of NewYork, have invented certain new and useful Improvements inHarvester-Binders, of which the following is a specification.

The harvester which I propose to use has its upper elevator-apronmounted in a frame overhung from the front of the machine, so as toleave an open throatway at the rear through which the heads of the longgrain may project as they are carried up; and my inventionconsists,among other things, in providing a swinging board or door forthis throat, hinged to the underlying strut, so that when turned up andsecured to the overhung apron-frame the throat Will beclosed and therear of said frame and the latter be supported from the strut, therebypreventing vibrations of the-overhung frame and disarrangement of itscanvas and rolls, and when turned down or opened it will aiford a tablefor and support the tops of longgrain projecting through the throat;also, in combining with such open throatway and with the bind ingreceptacle a detachable headboard or fence at the rear of saidreceptacle and supported rigidly from the harvester, so as to overhangthe receptacle and permit its free adjustment back and forth, alias willpresently appear.

In the drawings,Figure 1 isaviewin perspective, from. a point at theright and to the rear, of enough of an automatic binding-harvester toillustrate my invention as applied thereto. Fig. 2 is a similar view andfrom a similar po' sition, showing the rear or extension boards turneddown as to the harvester and that of the binder removed. Fig. 3 is anend elevation of a portion of the same, explaining the manner in whichthe binding-receptacle, with its hood, is adjusted along the end of thedelivery mechanism. Fig. 4: is a perspective view showing the cord-boxand tension de- 7 vice and illustrating the way the cord is run. v

Fig. 5 is an enlarged detail showing the man- 7 ner of securing the compressing-spring to the band-carrying arm, and Fig. 6 is an enlargeddetail explaining the mannerof securing the binder on the upper rails ofthe harvester. Fig. 7 is an enlarged detail, in rear elevation, of themechanism controlling the cut-off or separator.

O I A is the rear sill of the harvester-frame,

and A the front sil'l,which is usually a prolonbut inside the main wheeland furnishing the second or inner lateral bar of the wheelframe.

E represents the rear outer strut of the elevator-frame, and F theopposing or inner or tops of long grain and when turned up as a windboard or guard, H the main wheel, I the platform-carrier or lowercanvas, and I the stripper-roll at the head of the lower elevator-apron,all of which do not or need not materially differ from correspondingparts in machines already well known.

As heretofore constructed, the elevator is either closed entirely ateach side-fenced, as it wereor has an open throatway at the rear throughwhich the heads or tops of long grain may project. The open throatwayenables the manufacturer to very much narrow, and therefore to lightenand cheapen, the harvester and still carrylonger grain than a much widermachine with a closed elevator can carry; but it is sometimes necessaryor desirable, as in light puffy grain that is inclined to run back onthe machine, to have the elevator closed. To secure the advantages of aclosed elevator in a harvester having such an open throatway in therear, I attach to the inner rear elevator-strut a wing-board J, which isconnected therewith by hinges J and is prevented from-falling belowahorizontal position by a stop J that forms, in effect, a rule- Whenturned up, this keys J the former passing through holes J in saidboardthus supporting the rear end of said overhung frame and making itpracticall y rigid with the harvester-frame at that point. When it isdesired to prevent short or tangled or puffy grain from sliding back onthe apron or escaping from the harvester, the hinged rear boards of theplatform and elevator are both turned up, as shown in Fig. 1, to act asa rear fence or guard. If long grain is being harvested, these rearboards are turned down, as shown in Fig. 2, to clear the open throatwayand permit an uninterrupted flow of grain at the rear. In this positionthey support and bear up the heads or tops of the grain projectingthrough the throatway. This rear wing-board J is also hinged and made toturn up to form a rigid support for the overhung or float part of theelevatorframe for another and distinct purpose implied, but not fullysetforth, in the foregoing.

In the use of a harvester-binder having an elevator with a rear openthroatway and with its overhung frame entirely supported from the frontof the machine a very serious difficulty is met that often proves fatalto the successful operation of the machine. This difficulty is caused byvibrations set up in the necessarily light overhung elevator frame whenthat frame is not supported by the grain passing up the elevator towardthe binder. When the grain is so heavy and long as to require athroatway open at the rear, the canvas or belt rake carried by theoverhung frame rests on and presses down the grain, so preventingvibrations of the frame; but when the grain is thin and short it doesnot support the frame and vibrations, sometimes excessive and racking,as when operating in a stony field, are set up. These vibrations aresure to appear when hauling the machine along a common stony road to andfrom the field or from one field to another. The vibration of this lightoverhung frame racks and twists it so out of form and shape that therolls are cramped in their bearings and the canvas or belt-rake is soguided sidewise as to prevent it running, thereby choking down theelevator and stopping the machine. The cramping of the apron-rolls hasbeen obviated by some builders by joining the gudgeons to the rolls byuniversal joints. I avoid this difficulty by the, employment of thehinged win g-board J ,that when down secures an open throatway for thepassage of the long grain and a support for its heads, and when closedup and locked against the overhung frame, as when the open throatway isnot necessary, it binds and rigidly joins this float part of the frameto the main and lower frame of the elevator, thereby preventing allvibrations of the overhung frame and avoiding the abovenamcd serious andsometimes fatal difficulty.

The rear elevator-struts have usually heretofore marked the extremelimit to which the heads of grain have been supported in their passagefrom the delivery end of the platform-carrier to the binding-receptacle.The hinged boards just referred to in the present case project the firstof them beyond the rear sill and the second beyond the innerelevatorstrut, and thus support theheads of the grain from the dividerend of the platform to the head of the elevator, and that these headsmay continue to be supported in their passage down the grain-chute Isecure to the rear outside strut a wing-board K, that extends thegrain-chute rearwardly beyond this strut and at the same time owing toits location covers and conceals the drive-chain running up, as usual,alongside said strut. This I do not hinge or affix rigidly to itssupport, first, because it is intended to extend to or near to the footof such supporting-strut to act as a shield for the driving-chain, and,second, because if hinged it would interfere with the movement of thebinding-table, which must in its adjustments be free at all times toslide past it and reach its outer edge.

Lest the grain as it is being massed in the receptacle or upon thebinding-table may slip back or slide wholly out of the receptacle anddrop upon the ground at the rearof the machine a rear board L isprovided in the nature of a wind-board attach ed to the elevatorframe ofthe harvester and overhanging the receptacle, so as to fence it in atthe back of the machine. This rear board is not necessary and cannot beused in long grain. It is therefore made detachable at will, as shown inthe drawings, being for the purposes of this description held inposition by inserting the projecting foot of its cleat Z into the socketor mortise l, formed in the rigid wing-board, and by the button or clipL, secured to the rear bar of the overhung part of the elevator-frame.hen thus set up in position and secured by the button, it will pressagainst the upper end of the overhung frame and in connection with theoverhung supportingbar M will hold it against sagging. It is used inconnection with the hinged rear board of the ascendingside of theelevator and the hinged rear board of the platform when all three are ina vertical position to close up the entire binder and harvester at therear, and thus carry the grain through a closed passage from divider endto discharge end and insure that it shall not run so far back on themachine when tangled or disordered so as to bind poorly or not at all.On the other hand, when the rear board is detached and the hinged boardsturned down into a horizontal position an open throatway is afforded inthe rear throughout the entire length of the machine for long grain topass without hindrance or doubling the straw.

Upon the harvester is secured the binding attachment overhung at thefront by the usual stationary wind-board N and consisting in part of atable or receptacle 0, stationary shield O, fixed to the elevator-frame,

driving mechanism 0 and cast main frame or bracket 1, in the overhungtubular arm or sleeve P of which is mounted the binderarm shaft, andhaving at the rear end of this overhung sleeve an upright or standard I?for the support of the heel of the binder-arm,-

all in general as heretofore known.

The binder-frame has its feet P supported and sliding on rails p,attached to the stubble-girth of the harvester-frame, and the table orreceptacle, with its forks p, is supported and slides on rails 10attached to the elevator-frame, thereby enabling the whole bindingmechanism to be adjusted backand forth along the delivery end of theharvester by means of the lever Q, pivoted upon a bracket Q and lookinginto the interdental spaces of a segment-rack upon said bracket.

Secured to the rear end of the overhung sleeve of the main bracket is abar R, extending inwardly therefrom to near the headof the elevator andcarrying at its extreme inner end a bracket-casting S, one arm of whichextends directly to the rear and the.

other arm directly to the front and which has centrally or at the pointnear which the nose of the binder-arm plays an eye 8 and finger s forthe passage and" guidance of the bindingcord 8 whereby it is held inposition to be caught by the binder-arm as the latter descends. To thisbracket I secure the curved hood or deflector-plates T, between whichare the band-carrying arm T, and the trip-lever T loosely pivoted on theend of the trip-shaftt and engaging with a pin 25, adjustable in aseries of perforations t in a segment-armrigidly affixed to saidtrip-shaft during the operation of binding. This hood being rigidlyconnected with the main bracket or binder- .frame is carried back andforth therewith and with the binding-arm and trip-lever in all ad;

justments to the length of the straw, enabling the width of the slotbetween its two sections to be reduced to the minimum, and as itsupperend is brought by the cross-bar or supporting-bracket, to which itis secured, close to the head of the elevator it forms practically acontinuous closed passage at all times from said head to thebinding-receptacle to hold the grain down in the latter and prevents itsentanglement with the binder-arm. At the foot of each section of thisadjustable hood I secure to the binding-table curved circled and pressedby the binder-arm and is carried outward in the ejecting movement, whenthe table-springs will yield for its passageand immediately rise behindit to again closethe exit from the receptacle.

The binding-arm V3, which I have illustrated in this application,substantially resembles one described by me in an application heretoforefiled in the Patent Officethat is to say, it is supported from theupright sleeve of the main bracket by means of a link V, pivoted firstto said standard and then to the heel of the binder-arm, is operated bymeans of a crank V, secured to the binderarm shaft supported in saidsleeve, the wristpin of this crank taking into the binder-arm aboutcentrally of its length, and is provided with a spring V hooked into it,as at o, near its nose, and thence carried back, recurved, and at itsfarther end secured to the shank of the arm-=but I have changedthemethod of fastening it at this farther end and now form in the arm inthe act of casting a re cessed seat 2 into which the bent end 0 of thespringis inserted, as shown in Figs. 1 and 5, and in which it is firmlyand cheaply secured by clips or hook-bolts vipassing through the arm andheld by nuts or by riveting.

It is desirable that there should be a cut-off or separatorto act uponand hold backthe incoming stream of grain at the point where thebinder-arm shears off the gavel. This has heretofore usually been theoifice of an independent arm either moving up through the binding-tableor grain-chute or else moving down through the head or deflector. In myimprovement the office is imposed upon the trip-arm, and to this end thebinder-arm shaft or else the hub of the crank at the rear end of saidshaft is provided with a cam V which bar which carries the bracket-headfor the adjustable hood, is connected at its power end by means of alink V to the trip arm or finger and at its heel end has a shoe 0 toengage with the cam and beyond this shoe an inclined face 12 which meetsthe advancing end of said cam. The cam has the main portion of its face,except a slight outward spiral or incline behind theantifriction-roller, concentric with the axis of the bin der-arm shaft,and when in motion, the binding mechanism haV- ing already been startedby the trip-finger, this advancing end striking the incline at the heelend of the lever just as thebinder-arm descends to pierce the grainforces said trip- IIO finger down under cover of the binder-arm oralongside of it. As the binder-arm passes through and opens up a widepath by means armor standard at the rear of the overhung; accumulatingback of the separator is not large it may be released and allowed toresume its original function of a trip-finger as soon as the binder-armstarts on its return journey. This function it retains until thebinder-arm again descends for another bundle, when it is once more aseparator to aid the arm in making a complete division of the bundlefrom the incoming stream, as before.

The machine is supplied with binding-cord from balls carried in a caseW, mounted at the foot of the machine. The cord coming out of this casethrough the exit-orifice w is carried through a suitable tensiondevice-'for instance, the guides w, arranged alternately on each side ofa given line, so that the cord may zigzag through them-and thence goesto the binder in any way, as through the guide 10 and take-up 10 asshown, then through the guide-eye s in the deflector-bracket and pastthe finger 5 down to the holder, where its 'end is secured. Thebinding-arm, it will be understood, has no eye for the reception of thecord, but, like the one in my above-mentioned application, has a lateralflange which catches the cord-strands stretched between the finger s andholder near to said finger in each movement to divide off the gavel.
